What should you know about pale colour skin?

Paleness, also called pallor, may be easiest to see on the face, lips, inside the eyelids, gums, or palms. Skin tone, lighting, temperature, and recent fright or exertion can change how it looks. A brief change that returns to your usual colour may have a simple explanation.

Pale skin can be a presentation of anaemia, in which the blood carries less oxygen than usual. Iron deficiency anaemia and vitamin B12 deficiency are possible forms. Some inherited blood conditions, including sickle cell disease and thalassaemia, may also affect colour and cause other symptoms. Pallor alone cannot identify the cause.

Notice whether the change is new, widespread, or limited to one area, and whether it comes with tiredness, breathlessness, dizziness, a fast heartbeat, headaches, unusual bleeding, or yellowing of the skin or eyes.

Compare your colour in natural light and ask someone you trust whether they notice a change. Record when it started, whether it is constant, and any associated symptoms. Mention dietary restrictions, heavy menstrual bleeding, recent illness, long-term conditions, and medicines to a clinician.

A clinician may examine your skin and the inside of your eyelids and ask about circulation, diet, bleeding, and family history. Blood tests may be used to check for anaemia and deficiencies. Do not start iron supplements solely because your skin looks pale; treatment depends on the underlying cause.

Seek urgent medical help for sudden marked pallor with fainting, confusion, severe weakness, chest pain, trouble breathing, a cold clammy feeling, or heavy bleeding. These symptoms can signal a problem needing prompt assessment.

Arrange a medical review if paleness persists, keeps returning, or appears with ongoing fatigue, dizziness, headaches, breathlessness, palpitations, weight change, digestive symptoms, or unexplained bleeding. Seek advice sooner for a baby, child, pregnancy, or a person with a known blood disorder.

Ask: What areas should I check for pallor? Could my symptoms fit anaemia or a vitamin deficiency? Do I need blood tests? Could bleeding, diet, medicines, or a family blood condition be relevant? What changes should prompt urgent care?
